Application March 29, 1937, Serial No. 133,487

12 Claims.

This invention is an improvement in metal window framing constructionfor mounting and operative installation for use in connection with thesash. frame and housings therefor of my companion a'pplications'filedherewith Ser. No.

133,485 and Ser. No. 133,486.

'It consists in its entirety of stationary window framing portionscomprising top and bottom horizontal substantially similar head and sillmembers, and intervening vertical side framing por-' tions. Thesemembers are preferably made of extruded metal sections, for mounting ina window opening and in connection with the sash and housing elementsabove referred to. V

In. the accompanying drawings showing one preferred construction: f n

Fig. l is a sectional perspective view showing portions of a completeinstallation, including b'oth upper and lowersash and housing portionsin 23 their operative relation to the surrounding fram- Fig. 2 is asectional plan view on the plane of the section line II-II of Fig. 1;

Fig. 3 is a vertical sectional view on the line IIIIII of Fig. 2;

Fig. 4 is a cross section'on the line IV-IV of Fig. 1;

Fig. 5 is a sectional perspective view illustrating separability andadjusta'oility of portions of the framing construction;

Fig. 6 is a sectional view like Fig. l, showing means for connecting theinner channel and master plate to the surrounding framework.

While the framing construction may be used with other designs or formsof sash and housing, it is shown in combination with improved metallicforms, as in my applications above noted.

The light 2 is held within a surrounding frame between separable frontand back members 3 and 4, and mounted in a housing by connecting wedgeor dovetaili. The housing is thus fixedly connected with the sash frameso that they movetogether, and each housing is composed of a top bar 5,a bottom bar 1, these being reversed as. to

the upper sash housing, and side bars 8. The top bar 6 of the lowerhousing and the bottom bar 6a, of the upper housing are provided withinterengaging meeting rail sealing ribs 9 and 9a.

The bottom bar 1 of the lower housing and the top bar 1a of the upperhousing are grooved cdgewise for closing engagement with rib ID of ,thelower sill and rib Illa of the upper head member,"-preferably inconnection with aflanking rib H and Ha respectively.

Side bars 8 of each housing are alike and are similarly grooved forsliding engagement with ribs or tongues I2 of the window framing. Theyare also provided with sockets I3 for connection with sash cords M whichpass over pulleys l5 and connect with sash weights H3 in the usualmanner. I

The window framing construction with which the raising and loweringhousings and their sashes are combined and mounted for'operation is,like them, of metal, and preferably composed of extruded sections. Suchframing is mounted within w the window opening of a building upon thewooden or other opening defining construction comprising a lower sillframing member A, an

' upper head framing member B, and side framing members C. 5

The lower metal sill and upper inetal'head framing members are generallyindicated by the letters a and b respectively, and are substantially thesame, in reversed positions as shown, Fig. 1.

Each consists of an inner channel shaped one 20 piece section of thinsheetmetal having longitudinal side flanges H and a connecting Websection 18 deflected inwardly at the middle as at [9, for clearance ofthejoint connection of the outer retaining and finishinghousing-engaging por- 25 tions. 7

The flanges ll engage groovesin the wood or other framing A and B as at20 for fixed 1ocation therewith.

The housingengaging portions consist of a 39 pair of fiatsections' 2|,22,- ea ch having an outer flange 23 terminating in an inclined terminaledge 24 held in position by any suitable securing means, as screws ,25.Sections 2| and 22 have interlocking connection with each other within35 the deflected channel H! by tongue 26 and groove 2i engagement, eachmeeting edge being properly shouldered as shown for firm bracingconnection.

By such construction web sections Hand 22 are maintained in alinementagainst deflecting 1 pressure in either direction, assisted 'by innerchannel web l8. a

Section 22 is provided with the integral ribs or tongues i0 and 1 Landforms the inner halfof the lower sill framing, and in reverse position.5

forms the outer half for the upper sash housing,

as shown.

The pair of intervening oppositely located metal side framing membersare generally indicated by the letter 0, and are mounted between 5 theunder and overlapping ends of the sill and head members a and b.

Each consists of a channel shaped one piece section of thin sheet metal,having longitudinal side flanges28 also engaging grooves in the wood 55or other framing C, as at 29. The connecting web section 3|] isdeflected and shouldered as at II for holding engagement against lateralmovement of a master plate 32.

Said plate forms the base mounting of the laterally adjustable tonguesor ribs I2 and their bases 33, and of the main side walls 34 having thesash cord shrouds 35. These, as shown, extend over and cover the sidebars 8 of the sash frame. Master plate 32 is provided along and withinits opposite edge portions with undercut grooves 36 for holdingengagement by interfitting inclined wedging strips 31 of each side wall34 when they are in their normal outermost position and 'the parts areassembled for use, as in Fig. 4.

Bases 33 of slide ribs l2 have tongue and groove connection as at 38with the side walls 34 when both are in normal position, and both bases33 and their ribs are normally in operative relation to the sashhousings.

Bases 33 are held ,insuch outwardly spaced position by a pair of wedgingbars 39'having converging sides 40 bearing against theinner in- .clinededge faces 4| of bases 33.

, Each bar strip 33, shown as removed in Fig. 5, is .insertible inclearance opening 42 of plate 32 and held by several screws 43 tappedinto plates 32 and the middle preferably reinforced portion as in Fig.5, for access to the sash cord at either side.

An especial advantage in such removability of side sections 34 is thatthe entire sash housing and sash may be removed together with guide ribs12 and their "bases 33, without disturbing other portions. It will beunderstood of course that both-sections 34 at opposite sides vof onesash must be removed together to effect removal of a sash housing.

By making 'bar 39 in two sections, upper and lower, either may beadjusted by properly shifting one of the sash housings.

Channel 30 and master plate 32 are secured to the side framing C byelongated screws 44, Fig. 6,

and the endmost angular casing members 34 by screws 45 through theirterminal flange edges 46, or by any other. suitable means. 7

Sash cord pulleys l5 are pivotally mounted in shrouded brackets 41secured on the inner upper faces at each end of channel webs ID by apivoting and tightening screw 48 with the opposite end .of the bracketbase retained under a limiting flange 49, as in Figs. 2 and 3. By suchmounting the pulleys and brackets may be accurately located for propervertical positioning of, the two depending strands of cord I4 inconnecting its terminals with the housing bar 3 and sash weight isrespectively.

The channel webs 18, 2|, and 22 and brackets 41 are perforated as at 50for passage of the cords l4.

It will-thus be seen that by the construction of the several combinedelements and members of the window framing the three main metal units a,b and c are capable of very accurate mounting and cooperation with eachother, and that they provide for operative mounting within a' windowopening and for easy access to the working elements whenever desired.

Being made of comparatively light, thin, preierably extruded metalshapes, as of aluminum, the entire construction may be reduced tominimum dimensions externally, and in their entirety present anattractive, ornamental and durable equipment.

The several parts may be easily standardized and made to suit variousstandard typesas to size, etc., for different dimensional windowopenings.
